The Constitution Square can be regarded as the absolute city center of Mexico City. It is also a must for every visitor. The 55-meter flag is really shocking when it flutters in the wind. But to get the best angle, it's not the average tourist location, and it's enough to be lucky enough to book the best western top floor room facing the square. Pushing the window is such a scene, you can lie in bed and wait for the sunrise and sunset of Constitution Square.
